LIGHTING FIXTURE.

Application filed May 22, 1922. Serial No. 562,676.

My invention relates to the art of illumination and particularly to lighting fixtures employing a reflector and diffusion bowl, and has for its object to providea simple, strong, durable, inexpensive and adequate, means for holding the bowl in proper position to the reflector. A further object isto provide sucha means in a construction that will permit of the bowl bein easily and quickly attached or detached from the fixture.

-My invention consists of certain detailsof construction hereinafter set forth, pointed out in my claim and illustrated in the accompanying drawings in which Fig. 1 shows a plan view of a portion of a. reflector adapted for use in my construction;

Fig. 2 shows ,a side elevation view, partially in section, of a reflector, bowl, and my bowl holding means; and

Fig. 3 shows an inverted plan view of a reflector equipped with my holding means.

Referring to the accompanying drawings the reference numeral is used to indicate a reflector, preferably substantially flat on its reflecting surface, and the numeral 11 indicates a bowl to be attached to the reflector. The bowl I employ is of the usual type with a lip 12 moulded on its upper extremity,

the lip flaring outwardly as shown. Ob-

Y viously the opening at the upper part of the how]. is circular in conformation. The numerals 13, 14 and 1;) indicate bowl holding clips or lugs,the cl1ps'13 and 14 being rigidly affixed to the under surface of reflector and having downwardly and inwardly projecting body portions, as shown. The clip 15 has a downwardly and inwardly projecting portion, below the plane of the reflector, and a shaft 16 which projects upwardly through the reflector through an elongated slot 17.

The clip 15 after passing throug'h the orifice as described bends outwardly at substantially a right angle, thereby providing a shaft 18 which supported by a bracket 19 rigidly afiixed to the upper surface of the reflector, the said shaft passing through an orifice in the said bracket and being capped with a head 20, as shown. rounds the shaft 18, its outer end abutting against the inner surface of the bracket 19 and its other end abutting against a lug22 secured to the shaft 18, as shown.

A coil spring 21 surspring. Obviously the space between the bracket 19 and the outer flange of the reflector is greater than the length of the slot 17.

In practial operation a bowl 11 being des red to be attached to the reflector 10, the hp of the bowl 1s inserted between the lower surface of the reflector and the clip 15. Pressure is then put upon the bowl to force the clip 15 outwardly until the bowl has reached a position where the lip will be permitted to come in complete contact with the lower surface of the reflector, it having passed the points where the, lugs 13 and 14 would interfere with this. The bowl isthen moved until the lip is flush with the reflector and the pressure on the bowl is then removed, the tension of the spring being sufficient to force the clip 15 inwardly thereby seating the lip of the bowl between the clips 13 and 14 and the under surface of the reflector. Obviously these clips 13, 14 and 15 are all positioned to function in this manner.

Minor changes, such as a greaternumber of retaining clips, or a plurality of spring actuated retaining clips, and other changes, may be made in my construction without altering the spirit of my invention, the drawin'gs illustrating simply a preferred construction, and I do not wish to be understood as limiting the scope of my invention, ex cept as by the appended claim;

Having thusdescribed my invention, what I claim and desire to secure by Letters Patent of the United States, is:

In a device of the character described, the combination, with a reflector and a bowl having a lip formed thereon, of a plurality of fixed lugs secured to the reflector to engage the lip of said bowl there being an opening in saidreflector, a spring-actuated.
